TO ALL WHOM-KIT MAY CONCERN:

Be it known that I, HENRY G. NELSON, of Lockport, in the county of Niagara, and State of `New York,

have invented new and useful improvementsiin Water-Wheels; and I do hereby declare that the following is `a full and exact description thereof, reference being had to the accompanying drawings, making` a part of this Specicaton, in whichf- Figure 1 is an. elevation Figure 2, a vertical section. Figure 3, a top plan view.

Figure 4, a transverse section on line a b of iig. 2. Figure 5 is a perspective of the, bucket.

The nature of this invention consists of several distinct features, as set forth in the claims. i Letters of Vlike name and kind refer to like parts in each ot' the figures.

The lower part of the bridge tree or basin which contains the step a is shown et B. The arms of the bridge" tree, which take hold of and support the wheel case, are shown at B." These arms are made `concave `or lgrooved 'upon the inside, as shown, for the purpose of conducting water into the basin foiubricating the bearing of the shaft The lower half of the wheel ,whichcentains the reacting buckeissrepresented at C. This part is like the common and well known turbine wheel, and need not, therefore,.be more particularly described.4

The upper part of' the wheel, which embraces 4more Aparticularly my improvement,has tworims or hubs for supporting .the direct-acting buckets. The lower one of these is shown at D. Itis contiguous to and rests upon the top of the turbine. It is keyed orfastened to thewheel-shaft, and has on its outer-periphery vertical sockets for receiving the pin cast on the' lower edge of the direct-acting bucket, as shown at d. The upper rim or hub is shown at E. This is keyed to the wheel shaft in a manner to m'ake it adjustable thereon, so that it may be raised or lowered, and placed at any desirable point on the shaft, so that it may be accommodated to any length or size of bucket. My improved direct-acting bucket is shown 4in perspective in iig. 5. fl represents the vertical or direct-acting part of the bucket,and^f2 the reacting or standing part.A This part overlaps or connects with the turbine, bucketand, together with the turbine, forms the reacting' buckets.44 The body of .the bucket' is shown at f3. A bolt or screw g passes through this part and into the upper rim orihub, as' shown in' g.,2. On thc lower edge of this is cast a pin g', which enters the socket d. When the buckets are put on tothe hubs the contiguous edges of the. vertical or body part are halved, and overlap each other, as shown at f, iig. 4, so that by this overlapping, and with the bolts or screws gand pins g', the buckets are held securely in place. There is also a top-piece f5, which projects at right angles, or nearly so, from the body of the bucket, and overhangs, as represented in iig. 5. This bucket isv cast as a Whole in one piece. When the buckets are put on to the wheel as described, a circular metallic rim H is put over them, which projects a little beyond'the buckets, and exactly fills the cylindrical space within the wheel case, so that the water cannot escape upwardly from the buckets. This' rim is made in sections, andbymeans of slotted holes, through which thescrews or bolts z.

pass in order to fasten it on to the buckets, it is adjustable, so 'as-.to insure a perfect fit to the case to prevent the escape-of water upwardlys Thev gates and scrolls, which, together, form the chutes or water passages to the wheel, are placed in the wheel case I, and between the rims I2 I3. These togethr have a peculiar character and con-struction. The rigid scrolls .T are made stationary between4 therims, andere held firmly in place by the rims and the screw bolts K. lThey are placed atan angle and at aproper distance apart to direct the Watery jupon the wheel. The gates are `placed midway between the scrolls, and are hung upon the vertical shaft M. They are made of a proper length to reach from one scroll to another, so that when turned sufficiently they ,will shut o the water entirely from the wheel. When opened they form, in combination with the scrolls 1J, a full scroll or' chute to direct the water to the wheel. They may be opened and `set at any pointin eheh# movements() as to admit a greater or less quantity of water to the wheel, as may be desired. These g'aftts are 'operated by means 0f the segment ringN, pinion O, pinionfshaft and slotted arms Q. The slotted arms Q are fitted each to the top of thegatashaft M, and there is a pin projecting from the under side of the segment ring., which drops into the slot in each armfoi-,the purpose of communicating motion from the ringn to the arms, and yhence to the' gates. Friction rollers S are placed inside of the ring,whchvhave a. ilangeu, whichoverlaps the ring slightly and holds it down in its proper place. New it will be seen thatthe combination and arrangement of these parts is such that, by turning the hand-wheel V, a simultaneous' movement will be communicated to each and all of the gates, and that the gates will be held in anyi'equiredpositiaintgy as placed. The operator at the hand-wheel has perfect control over all of the-gates, to give each and all an equal movement, and'thereby insure an equal quantity of water to be discharged throughv each scroll, and. hence'v 'an equalquantity of Water upon each side of the wheel. l i

What Ilaim as my invention, aud I esire to secure by Letters ,Pat-ent, isf- 1. Making the arms of the bridge .tree grooved, for the purpose of 'conducting water into the step for lubrication," substantially as described. v

2'. The adjustable' hub E in combination with the hub D for the purpose, and substantially' as described.

3. lvaterawheel bucket, having the parts f1, fz, f3, and ff' inl combination, substantiallyas set forth.

4. The .stationary scrolls J and horizontally moving gates L, when arranged Witha segment ring N,

operating gear and arms-Q, and friction rollers S as a means of opening andclosing the gates L, substantially Y as described.
